When you use an Optoma projector for a presentation or a film-watching activity, you usually adjust the settings before you start, to provide your audience with an excellent viewing experience.
Typically, you would select the appropriate projection orientation, update the image and display settings, etc. Other times, you will lock the unit to keep other people, perhaps younger audiences such as kids, from adjusting the projector settings by mistake.
Often, you will have a problem changing the settings back, leaving you with a locked projector that won’t respond to any button you press on your remote.
While this may sound dumb, it is a common inconvenience Optoma projector owners encounter.
Unlocking an Optoma projector is easy. In this article, we will walk you through what to do and provide you with detailed steps to unlock your projector.

How to Unlock an Optoma Projector
There are two instances wherein you will need to unlock your Optoma projector:

Below are the steps for unlocking your Optoma projector:
Locked Keypad
If your Optoma projector keypad is locked, there are two methods you can use to unlock it.

Security Password
In case your Optoma projector has a security feature activated, you will need to enter a passcode each time you power it on.
Follow these steps to permanently unlock the security passcode:
- Press the Menu button on your Optoma remote or its panel, and go to the Setup tab.
- Select Security, then toggle Off the Security feature (If you have set a passcode before, enter it when prompted. If not, use the default passcode: 1 2 3 4 or 0 0 0 0).
If you wish to activate the security feature and set a new password for your Optoma projector but have forgotten the previous passcode, performing a factory reset is your best option (proceed to the next section).
